build: remove src/*.bak from distribution

Instead, include the autogen-generated *.c, *.h and the stamp files in
the distribution.

To prevent the bundled files being linked with incompatible autogen
libopts, this adds an extra check in configure.  If the detected
system libopts version is too old, it will use the included libopts
implementation.
